Exam 1 Flashcards
ACE (in terms of pain)
Assess: for pain and rating
Care: manage patient
Educate: addiction, don’t wait until pain is severe
When do you see side effects of a med
Peak
IASP definition of pain
An unpleasant sensory and emotional experience associated with actual or potential tissue damage, or described in terms of such damage
McCaffery’s definition of pain
Whatever the pt says it is, whenever the pt says it is
JHACO standards (2)
All pts must be assessed for pain
All pts have the right to appropriate assessment and management of pain
Peak respiratory depression (IV, IM, SQ, epidural, transdermal)
IV: 15 min
IM: 30
SQ: 90
epidural: 6-12 hrs
transdermal: 12-18 hrs
Joint commission accredits pain specific components such as (4)
location
onset
alleviating factors
aggravating factors
Adaptation response
pt has pain but doesn’t show parasympathetic symptoms; withdrawal from social interactions & depression seen
Nociceptive pain and 4 steps
Normal
transduction (pain converted to electrical impulse in horns)
transmission (neurotransmitters regulate pain perception and go to cortex)
perception (we understand the pain)
modulation (modulate the pain)
endorphins
body’s natural morphine system, delays transmission of pain (also from placebo)
neuropathic pain
nerve injury usually peripheral
ex. diabetic neuropathy or phantom pain
Pain STIMULATING chemicals (5) and what do they do
histamine
bradykinin
acetylcholine
potassium
prostaglandins
they stimulate the inflammatory process
Pain CONTROLLING chemicals (3) and what they do
enkephalins
endorphins
serotonin
They modulate the pain
Biologic pain
Internal
Chemical pain
Caused by internal chemical, such as ulcers
Physical pain
caused by outside stimuli, like a tight cast
chronic intermittent pain
comes and goes like migraines
cancer related pain
from disease progression and treatment options
superficial pain
cutaneous, like a cut
Deep somatic pain
bone, muscle, blood vessels, connective tissue
visceral pain
pain from internal organs
localized pain
confined to site of origin
referred pain
pain that is felt somewhere else (like arm pain from an MI)
Intractable pain
high resistance to pain relief (nothing works)
Breakthrough pain
pain that occurs between doses of pain meds
acute pain
Mild-severe
sympathetic NS responses (observable)
related to a specific injury
resolves with healing
restless and anxious
reports of pain
pain behavior
definite start, occurs as a result of an injury, definite end time
Chronic pain
mild-severe
adaptation response
parasympathetic NS responses
cancer related pain
progression of cancer
treatment
acute or chronic
need large dose of pain med
Adaptation response
vital signs
facial expression
shifting away or guarding
reporting pain only if asked
sleepiness
limited physical activity
withdrawing
pain in the elderly
typically passive, may deny pain (ego or “normal” feeling)
more sensitive to drugs
chronic pain undertreated
sleep deprivation and fatigue=longer healing time
addiction
compulsion characterized by behaviors that include impaired control over drug use, compulsive use, continued use, despite harm and craving mostly for psychic effects
dependence
opioids taken over a long period of time with abrupt cessation, rapid dose reduction, decreasing blood level of the drug, and/or administration of an antagonist
not an addiction
state of adaptation
physical dependence
drug class specific withdrawal syndrome
physical withdrawal, suddenly stopped
Psychological dependence
emotional craving for drug effect
prevent occurrence with withdrawal symptoms
tolerance
decreased sensitivity to analgesic
properties of opioid with need for increasing doses to maintain level of pain relief
adequate pain relief no longer obtained
state of adaptation
pain assessment
triggers/relief
associated s/s
intensity (scale)
threshold (when they feel pain)
tolerance (max amount of pain someone is willing to take)
location
quality
onset and duration
personal meaning
allergies
OPQRST
objective signs
provoked by what
quality
region
severity
timing
objective pain signs (5)
sympathetic, parasympathetic, verbal, nonverbal, adaptation response
unreliable on their own
what do we want to do when managing pain (6)
reduce anxiety
prevention (periodic meds)
PCA
placebos
anesthetic blocks
non-pharmacological
what do placebos set off
the internal morphine system
adjuvant analgesics (4)
Given with or in place of other pain relief meds:
steroids
antihistamines
anticonvulsants
antianxiety
non-opioid analgesics
salicylates (aspirin)
acetaminophen (tylenol)
NSAIDS
aspirin side effects (2)
tinnitus
decreased effectiveness of NSAIDS
NSAIDs side effects (2)
increased sodium retention
GI bleeding and irritation
take with food or milk
adverse effects of opioids
resp depression
tolerance of side effects:
itching (solved with benadryl)
constipation (ambulate)
what does massaging do
releases internal morphine (endorphins)
contralateral stimulation
massage opposite of where injury is
diathermy
pulsations (like a sonogram), produces heat
what is TENS used for
intractable or chronic pain
nursing problems: pain
fatigue, impaired mobility, self care deficit, ineffective airway clearance, impaired gas exchange, hopelessness, ineffective coping, ineffective health maintenance, disturbed sleep pattern, deficit knowledge
Functions of body fluids (4)
transport nutrients to cells and waste away
maintain homeostasis
tissue lubricant
temperature regulation
ICF amount
2/3 of our body water
40% of our weight
ECF amount
1/3 of our body water
20% of our weight
intracellular spacing
1st spacing
when fluids are where they’re supposed to be
extracellular spacing
2nd spacing
fluid leak-edema
transcellular spacing
3rd space
synovial, CFS, pericardial, pleural [effusion- ascites], intraocular (areas with little to no water usually)
fluid is trapped
must be removed with a needle
leads to hypervolemia/weight gain
dehydration vs hypovolemia
dehydration: only ECF, electrolytes become more concentrated
hypovolemia: ICF and ECF fluid volume deficit, loss of electrolyte (ex. hemorrhage)
hypovolemia manifestations (8)
oliguria, tachycardia/pnea, generalized edema (non pitting), weight gain, fever, constipation, abdominal cramps
solvent
the liquid doing the dissolving
solute
the stuff getting dissolved
hydrostatic pressure
pushes fluid out of capillaries (interstitial space) and into interstitial fluid
plasma colloid osmotic pressure
holds fluid inside the capillary
pulling force of albumin
albumin holds fluid in capillaries, important w edemas
kidney failure=disruption
what happens when kidneys can’t filter out protein
kidney increase in colloidal osmotic pressure
how do age and body fat content affect fluid and electrolye balance
Age: body fluids increase in younger than older
Body fat content: thin and women> obese and men bc fat cells/adipose tissue have little water
GI factors effecting fluid/electrolyte balance
nasogastric suctioning, vomit, diarrhea
environmental factors effecting fluid/electrolyte balance
vigorous exercise, high altitudes, dry climates, alcohol, caffeine, diuretics, heart and blood vessels, respiration (insensible water loss)
hypovolemic shock
bad
temp regulation (up to 105F)
impaired thought process
sodium loss (abdominal cramps)
Behavior, skin, tongue, vitals, etc in fluid volume deficit
behavior: confusion, combativeness, coma
flattened veins, oliguria, dark, high specific gravity
skin: poor turgor, loss of IS space fluid
tongue: dry and furrowed
vital signs (low BP, high HR, high temp), SOB, paresthesia, muscle cramps
neuromuscular irritability
fatigue
nursing management of FVD
identify and assess, look to replace I&O, daily weight, abdominal girth measuring
FVD related factors
decreased fluid intake (imposed fluid restriction, inability to swallow or obtain fluids)
depression
increased needs for fluids (strenuous exercise, extreme heat or dryness, fever)
abnormal fluid loss (V/D, abdominal surgery, abnormal drainage, skin trauma, laxatives, enemas, blood loss, diaphoresis, polyuria)
